<H3><A NAME="6_5_1">6.5.1 Clipping</A></H3>
<P> By default plots are not clipped outside the plot area for
 performance reasons.</P>
<P> This means that if you have manually specified a scale range and
 your data is outside that range the plot will be drawn outside the
 scale and into the margin.</P>
<P> The clipping algorithm is &quot;perfect&quot; in the sense that for example
 line plots where the plot area cuts the line between two data points
 the line will be drawn up to the edge of the plot area. The algorithm
 used is O(1) in number of data points.</P>
<P> The disabling/enabling of clipping manually is controlled by <A href="../ref/Graph.html#_GRAPH_SETCLIPPING">
Graph::SetClipping()</A></P>
